Abstract: A hot sprue valve assembly is provided for controlling flow of molten material into the mold cavity of an injection molding machine. The valve assembly is particularly designed for use with an injection molding machine for molding centrally apertured record discs, such as video information discs. The valve assembly includes a hot sprue bushing defining a heated flow path for passage of molten material toward a stationary dispersion head positioned centrally within the mold cavity. The dispersion head directs the molten material to flow in a generally radially outward direction with substantially uniform radial distribution into the mold cavity. A cylindrical sleeve valve is carried about the hot sprue bushing for reciprocal movement between an open position retracted from the mold cavity to permit flow of the molten material into the mold cavity, and a closed position projecting into the mold cavity in seated engagement with the dispersion head simultaneously to prevent flow of the molten material into the mold cavity and to mold a central aperture in the disc.

Abstract: The feeler in the tooth flank profile measuring apparatus for determining the roughness of the tooth flank surface comprises a Hall-effect sensor placed in a static magnetic field between two permanent magnets instead of the otherwise conventional piezo-electric or inductive measuring system. One of the two permanent magnets is adjustably mounted at one end of a feeler rod or arm which carries at its other end a feeler tip for scanning the tooth flank surface. A conventional cross-spring joint serves to rotationally mount the feeler rod or arm. The cross-spring joint need not be distorted or loaded for adjusting the bearing load of the feeler tip because there is provided for this purpose a magnetic bearing load adjustment device. The magnetic bearing load adjustment device not only compensates for the biasing force of the two permanent magnets of the measuring system, but generates a selectable bearing load for the feeler tip by overcompensating for the biasing force of the permanent magnets of the measuring system. This selectable bearing load for the feeler tip can be already measured during the adjusting operation. Since this bearing load is generated by the magnetic fields and since the cross-spring joint need not be distorted, the feeler has a substantially greater mobility and a substantially wider frequency response compared to known feelers. The feeler additionally has a simpler mechanical structure and the circuitry in the evaluation circuit is substantially less complicated in comparison to known feeler arrangements.

Abstract: A method of forming an electrically conductive pattern on a substrate includes the steps of forming a layer of gold (6) on an electrically insulating substrate (2) and coating the gold layer (6) with a photo-resist (8). The resist (8) is exposed to light through a photo mask and the exposed portions of the photo-resist (8) are selectively removed by etching. The now exposed parts of the gold layer (6) are coated with copper (12) and the remaining photo-resist (8) is removed. The exposed parts of the gold layer (6) and the copper (12) are subjected to molten tin (14) which simultaneously acts to dissolve the exposed parts of the gold layer (6) and to form an electrically conductive coating on the copper (12).The process enables the formation of a precise conductive pattern with enhanced reliability.

Abstract: The disclosure relates to automatic guns in which there is included an apparatus for increasing the rate of fire of the gun. The breech mechanism of the gun is controlled by means of recoil movements which arise on discharge of the gun and by an operating cam (5) and spring member (7) included in the mechanism. Two case ejectors (18) are disposed to arrest the breech block (2) in the region of total recoil position of the breech and to hold the breech block in the open position in order thereby to make for ramming-home of a new round (19). In the arrested position of the breech block, the ejectors are exposable to the new round during its ramming cycle. A portion of the kinetic energy inherent in the round is transmitted to the ejectors which, in such an instance, may accompany the round and release the breech block so that this is actuated towards its closed position by the spring member (7). The operating cam (5) is movably disposed at least when the breech is located in the region of its total recoil position. The spring member may, in this manner, begin to actuate the breech block on its movement towards the arrest position at an earlier stage than has hitherto been possible.

Abstract: A safety stoppage or disconnection apparatus for mechanically moved tools, particularly automatic welding guns, having a swashplate and an assembly casing, between which are arranged one or more spring elements and a switch operated by the relative movement between the swashplate and assembly casing. It is necessary with such safety apparatuses to prevent other adverse rotary movement between the swashplate and assembly casing. This is brought about by two facing bolts, whose heads projecting beyond the outer wall of the swashplate are guided in slots, which run in the inner wall of the assembly casing in the intended swashplate movement direction. The bolts are spring-loaded and preferably spherical. The bolts with the spherical heads on the one hand reliably prevent a rotary movement between the swashplate and assembly casing and on the other hand do not prevent the relative movement and a slowing down movement necessary for the operation of the switch, even if the swashplate is tilted and tipped by the relatively large moment exerted by the tool against the swashplate. Following tool relief, the swashplate returns in an unimpeded manner to its initial position.

Abstract: The industrial truck or vehicle comprises a support body or member supporting an elevatable platform. The support body is supported and guided on both ends by a respective transverse pivot joint of a respective driving module or unit. The width of the support body and the platform is narrower than the width of the two driving units. This narrowing or reduction in width of the industrial vehicle ensures that the complete platform region on both longitudinal sides of the industrial vehicle is manually accessible despite providing good lateral vehicle stability. Furthermore, the torsional elasticity of the support body is increased such that the support body in combination with the transverse pivot joints provide sufficient travel surface adhesion or floor traction of all drive wheels and support or free-running wheels even over irregular or uneven travel surfaces. The industrial vehicle possesses an emergency recovery device so that it can be temporarily driven without auxiliary devices if up to two wheels become blocked. For this purpose the driving units are tilted individually or in combination about the still functional wheels by means of a respective drive spindle until the blocked wheels are free of the floor or ground surface and the industrial vehicle is rendered mobile. The reduction in width of the industrial vehicle and the autonomous capability of recovering from emergencies permits this industrial vehicle to be utilized in flexibly-organized assembly plants, especially in the automotive industry.
